\ VEHICLE-GEAR.

Specification of Letters Patent.

Patented Dec. 14, 1915.

Application flied September 9, 1912. Serial No. 719,388.

To all whom it may concern:

Be it known that I, CHARLES A. Wmnno, residing at Chisago City, in thecountyof Chisago and State of Minnesota, have 1nvented certain new anduseful Improvements in Vehicle-Gear, of which the followin is aspecification.

y present invention which generally relates to improvements in shortturning gear for carriages, wagons and the like, more particularly hasreference to the type of short turn vehicle gear disclosed in my patentdated March 5, 1912, No. 1,019,108, and my said present inventionprimarily has for its purpose to provide a new design and arrangement ofthe mechanism generally disclosed in my patent aforesaid whereby theefliciency thereof is greatly enhanced, and the cost of manufacturematerially reduced.

Another object of my present invention is to provide for a simpllfiedand practical means of mounting the wagon body and for the convenientapplication of mud guards for the front wheels of the vehicle.

With other objects in view that will hereinafter appear my presentinvention embodies the peculiar arrangement and novel combination ofparts all of which will be hereinafter fully explained, specificallypointed out in the appended claim and clearly illustrated in theaccompanying drawings in which Figure 1, is a perspective view of avehlcle with running gear constructed in accordance with my invention.Fig. 2, is a front elevation of the front axle with the improvedattached parts (the tongue member being shown in section). Fig. 3, is aperspective view of one of the axle carrying heads or knuckle membershereinafter specifically explained. Fig. 4, is a plan view of mycomplete improved running gear, the body supporting springs being alsoshown. Fig. 5, is a side elevation of the mechanism shown in Fig. 4, aportion of the vehicle body being also indicated. Fig. 6, is a detailperspective view of the rod that connects the opposite knuckles or axlecarrying heads. Fig. 7, is a detail cross section on the line 7-7 onFig. 2. Fig. 8 is a detail view of the hub dust cap.

In carrying out my present invention I provide a front axle formed oftwo sections designated 23 in the drawings, each of which is formed witha centrally disposed ofiset whereby, when the two parts are assembled, ahorizontal slotway a is provided, whose opposite ends terminate inopposing bevel-like shoulders 5-0 (see Fig. 4) the purpose of which willpresently appear. At the opposite ends the axle sections terminate 1noppositely inclined portions d, which form bifurcated bearings 6 havingapertures for the stud ins 9, that constitute the pivots for thebifurcated ends 40 of the axle carriers or rocker heads 4, the detailedconstruction of which is best shown in Figs. 1 and 3, by specialreference to which it will be noticed the rocker head 4 has a stub axle44 integral therewith and a rearward extension or arm 41, the outer endof which terminates in apertured ends 42, for receiving the pins 43 thatconnect the ends of the single transverse rod 13, presently againreferred to. Axle 44 has a lateral opening projecting into a slot 70 ofthe axle skein that slips onto the axle and whose inner end carries adust cap or guard 71, as shown.

Cooperating with each of the rocker heads 4 is a lubricating means inthe nature of a compression grease cup, that includes the grease holder5, the adjustable plunger cap 50, a set screw 51 for holding the cup toits adjusted position and the feed channel 52 that extends down alongthe axle to feed the lubricant between it and the axle skein.

The axle members 2 and 3 are made fast as one by the bolts 24. Thewheels 8 are mounted on the axles and held by the axle nuts in theordinary manner.

1 designates a tongue section which acts as a fifth wheel, it having anextension 11 that passes through the slot a in the front axle and ispivotally held on the king bolt 25, its rearwardly extending portion 11passing into the slot 14 of the single transverse bar 13, as is clearlyshown in Figs. 1

p and 2.

By reason of the peculiar and novel arrangement of the gear mechanism sofar as described it will be readily apparent that when the vehicle isturning, the lateral sweep of the pole 23 will shift the transverse bar13 in the required direction and in consequence turn the front wheels 8to cause the front end of the vehicle to make the quick and desiredshort turn, the side turning of the said wheels being held from scrapingthe vehicle body by reason of the beveled stop shoulders bc with whichthe tongue member engages when swinging too far laterally.

In the complete arrangement of my present invention, I mount the wagonbody on two sets of springs, those at the front end being designated 15and those at the rear end 16. The springs 15 are of the laminated typeand are clipped or otherwise fastened on the forward end of the side orreach bars 17 ofthe running gear, .the free ends thereof being connectedto a cross rod 18 to which a second set of springs 19 are joined thatare secured to the bottom of the front portion of the vehicle body.Springs 16 are likewise joined by a cross rod 26 to which connect asecond set of springs 27 that extend forwardly over the sides of therear ends ofthe vehicle body and are bolted to side brackets 28 securedto the said body, as clearly shown in Figs. 1 to 4.

To take up excess strain on the body supporting springs when going oververy rough road surfaces the vehicle body has bumpers 3334 and tofurther avoid undue strain on the forward springs cushion bumpers 35 aresecured on the under side of the front end of the said vehicle body, asshown.

36 designates a brace bar bolted to the side or reach bars, and 37designate the side steps mounted in the lower ends of hangers bolted tothe side or reach bars and the said steps have a series of apertures 38to provide for the convenient attachment of the front wheel mud guards39, the front ends of which are supported by stay members 32, secured tothe front axle, see Fig. 1.

A suitable dust cap 80 may be secured over the wheel hub ends asindicated in detail in Fig. 8.

,From the foregoing taken in connection with the accompanying drawings,the complete construction and arrangement of the parts that constitutemy invention and the advantages thereof will be readily apparent.

What I claim is:

In a short turn gear; a front axle consisting of two bars 23, bolts 24securing said bars flatwise together, the ends (1 of said barsdiverging, said bars having central recesses to form a central slot (1,the side walls I) of which are beveled to form tongue movement limitingstops, a tongue section 1 passing through said central slot, a bolt 25on which said tongue section is pivoted in said slot, a knuckle bearingpivotally mounted in each end of said axle between the bifurcations ofthe same, and each of said knuckle bearings including an axle spindle 7and a lateral member 41 that projects rearwardly relatively to the frontaxle, a single cross bar 13 having its ends pivotally connected to saidrearward extensions 41 of the respective knuckle bearings, said singlecross bar 13 having an elongated fiat eye 14 intermediate its ends toreceive the end of said tongue section 1, and a pivot passing throughsaid eye 14 and said tongue section 1, and a draft tongue 23 pivoted ona horizontal axis to said tongue section 1, all being arrangedsubstantially as shown and for the purposes described.
